It came out with the figures that i needed, but what i need to know is what is the difference between Horizontal & Vertical Scheimpflug ?? And how do i translate that to the lenses on the PJ ?? (Barco Data 801s)

Just show's you the washers in the manual, ok i can pack the washers to the details from the lens program. But how does this information translate to the lens studs ?? And which studs are horizontal and which are vertical ??

The focus is correct when it is the same sharpness across the screen. Having said that optics are never perfect and the corners may always be a little less sharp. However they should all be the same.
The bars on a barco test pattern are wider vertically than they are horizontally.

The Electronic focus and asitigmatism were set up correctly when I sold it to you. I see no reason why they should need to change.

I'll keep playing with the edge focus, and i don't need to worry about the Astig & electronic focus.

When i was doing the focus, i just noticed the bars on the "Nokia Test Program" do have a flared edge to them.

I suppose this still means that the focus isn't 100%, and the convergance still need tweaking. As i can see a blue haze above and below some horizontal lines on the blue tube ?? (That's on screen and not on the CRT !!) Red looks pretty good.

And the other thing i know i'm not going to get the blue as sharp, as the red & green, as blue is the most difficult to set-up, and prefers to be just off focus. (Is this correct ??)
